Oxidative stress is the most studied subject related to most all diseases. If you go to www.pubmed.gov and put it in the search bar--you will see over 100,000 studies on most diseases. If you want to see how many studies related to a given disease put in the search bar oxidative stress cancer (or any other disease) The more studies, the greater the link. Ataxia has not been around as long, but check it out. Another site is www.oxidativestressresource.org If you like to research as I do, use www.googlescholar.com rather than google--it eliminates the spam and only has validated info. If you want to see an ABC news piece about it, see www.abcliveit.com I found out about it about 2 years ago and it gave me my husband back. If you have questions or want to order it ($40 month +tax) you can contact me at ■■■■■■■■■■■■■■■■■■■ or order at www.mylifevantage.com/joywellness We are all here to share info and help get relief. That is my hope for each of you. Joy
